Justification:
Listed as Data Deficient on the basis that, although its known habitats are difficult to access and subject to no apparent threats, it is limited to very restricted and isolated subpopulations and has a very narrow ecological niche. More research is therefore needed to establish whether it is able to persist in these fragmentary populations, and whether it is sensitive to even light levels of disturbance.

This species is found in southern Yemen and Oman. In Oman it has a restricted distribution in Wadi Ayun and another site in the Dhofar region, and Jabal al Qamar Wadi, in the mountains near Mugsayl (van der Kooij 2000). In Yemen it is known from Wadi Hajr and Sayhut. It has been found up to 800 m asl.

It appears to be strictly nocturnal (Arnold 1980). This species is only found on very large water-smoothed white marble bounders in the bottom of wadis (Arnold 1980; van der Kooij 2000). They are very adept at climbing in this slippery habitat (van der Kooij 2000). It appears that the spatial niche occupied is particularly narrow, and is very discontinuously distributed (Arnold 1980).
